The 217 lt. capacity open-head ISO CONTAINER, also called TAPERED drums, are produced in compliance with UNI EN 209. They are made of DC 01 steel in compliance with UN 10130 - 10131.
The body is assembled longitudinally by electric seam welding of the overlapping edges and is fitted with ISO CONTAINER expansion elements to reduce the size of the diameter to that of tight-head drums.
The bottom is assembled to the body by triple seaming with sealing mastic inserted between the two parts, whilst the top or removable lid is closed air-tight with the aid of a hydraulic press (3bar) with a galvanized lever lock ring. The drum has two openings (G 2" and G 3/4") closed with metal bungs.
External surface painted with oven-baked water soluble enamel.
Models of this type of drum have also been approved for solid, with or without openings. Different thicknesses and internal coatings can be chosen according to the user's safety requirements.
